This invention relates to laundry driers. An object of the invention isto provide an improved device for drying laundry comprising anenclosingcabinet for the laundry to be dried, vin combination withimproved means for producing heated air and driving the heated airthrough the cabinet.

Another'object ofthe invention is to provide a laundry drier of thecharacter and I0 type mentioned wherein the cabinet is provided with adoor or closure for the top, and meansv cooperating therewith to stopoperation of the mechanism that forces the heated air through thecabinet automatically and as an incident to the opening of the top ofthe cabinet. Y c

Another object of the invention is to provide a top closure for a dryingcabinet having means on opposite sides for. engaging and supportingthefabrics vto be dried so that the fabric may be placed upon the upperside' of theclosure while the4 fabric on the opposite or inner side ofthe closure is being dried. Y

Other objects will appear from the following description, referencebeing made to the drawings in which Fig. 1 is a plan view of my improvedlaundry drier, part of the cabinet walls being '30 shown in section andthe top kclosure being shown in open' position.

Fig." 6 is a diagrammatic view of the electric circuit same.

My improved dryingl cabinet comprisesV two side walls Y'1, a rear endwall 2,a'front end wall 3 and a bottomV wall 4. f

The front end wall 3 has an opening therethrough which is surrounded bya frame 5 in which is mounted a device 6 constructed and arranged on theprinciple of an automobile radiator so that water or steam may passfreely therethrough. This radiator 6, being constructed and 'arranged onthe principle andthe switch controlling the Y l of an automobileradiator, aslstated, has a large number of openings through which airmay be forced from the outside to the inside ofthe drying cabinet.

A manifold 7 has a number of tube or pipe connections 8 Opening into theupper side of the radiator 6 and controlled respectively by valves 9whereby the amount of steam passing into and through the radiator 6 maybe controlled and regulated. The manifold 7 receives steam from a steamsupply pipe 10Y leading from some suitablev boiler or source of supply.

vA number of pipes 11 open from the under'. side of the radiator 6 intoan exhaust manifold l12 from which the steamis conducted to waste ordischarge through an ex-V haust pipe 13. A blower 14 is supported withinthe frame 5 adjacent to the outer side of the radiator 6.' This bloweris on a rotary shaft 15 driven by an electric motor 16, the wiring 17 ofVwhich is controlled by a switch 18.

Y A confined space 19`.(Fig. 5) is formed on the inside of the oppositeend of the cabinet by av box 20`havin`g an inlet slot 21near its upperedge. "T he space 19 opens into anumber of pipes 22 which extendlongitudinally Y through the cabinet andrjout through openings in theopposite endwall 3. Thus, the hot air that is driven into the cabinetthrough the radiator 6 passes through the opening 21 into the enclosure19 and thence to exhaust through the pipes21. Accordingly,`any fabricsthat are supported in the cabinet are subjected toa continuous currentof hot dry air sothat the fabrics are quickly dried. c Y The closure forthe'upper end of the cabinet comprises a pair vof spaced walls 23forming opposite sides `ofa frame2l1 which is rotatively supported near'thetop of the cabinet by axial extensions 25. VOn each side ofthe frameV24 fabric engaging devices A26 are secured and these may bemade orcomposed of -carding brushes. Thus, it 1s apparent that when eitherside-of the closure is toward the inside of the cabinet a fabric may besecured to the outside of the closure. while the fabric on the inside isbeing dried.

EBI)

The wire 27 from the motor leads to a contact member 28, while the wire19 from the switch 1S leads to connection with a spring element 29 (Fig.6). A stem 30 is mounted in the wall 3 of the cabinet and projectsthrough the spring member 29. The stem has a collar 31 which is engagedby the spring element 29 so that said spring element is effective tomove the stem 8O out of contact With the contact member 28 when there isno pressure against said stem 30. Near each side of the frame 24 Iprovide a bowed member 32 which will engage the end of the stem 30 andpush said stem in opposition to the spring member 29 to contact with thecontact member 28 and thus close the circuit through the motor when theswitch 18 is closed. However, when the frame 28 is moved out of closedposition it is obvious that the bowed member 32 will be moved away fromthe end of the stem 30 and Will permit the spring member 29 to open thecircuit by moving said stem 30 out of contact with the contact member28. In this way operation of the motor 1G and the blower 14 is stoppedautomatically and as an incident to the opening of the cabinet. That isto say, Whenever the frame member 24 is turned on its axis from closedposition the motor and the blower are stopped. This is quite anadvantage inasmuch as the air within the cabinet becomes very hotA andif the blower continued to operate during the opening of the cabinet theoperator wouldv be subjected to the extreme discomfort of the intenselyheated air.

In operation the frame 24 is turned to closed position and the fabricsecured to the upper side` thereof by engaging the fabric with theholders 26. Then, the position of the frame is reversed so as to placethe fabric at the underside of the frame and within the cabinet. lVhenthe switch 18 is closed, `the frame 24 now being in its closed position,the motor 16 begins to operate and thereby operates the blo-wer 14driving air through the hot radiator 6 to the inside ofthe cabinet andthence out through the exhaust pipes 22. IVhen the 'fabric is dried theframe 24 is turned over to reverse position so that the dried fabric isat the outside anda fabric to be dried is on the inside of the cabinet.An an incident to the movement of the frame 24 from closed position themotor is stopped, as above explained. As the frame 24 is moved to closedposition to place the wet or damp fabric Within the cabinet and the dryfabric in position for removal at the outside, the bowed element 32closes the switch to the motor so that the motor automatically starts.

From the foregoing it will be seen that my invention is of a highlyuseful and simplified construction and possesses many advantages in thatthe motor is automatically controlled for the most beneficial results.Obviously, the construction and arrangement of the parts may be variedWithout departure from the nature and principle of the invention.

I contemplate such variations as may be deemed useful and do notrestrict myself unessentially in any particulars, but what I claim anddesire to secure by Letters Patent is 1.
